Pharrell -- Nazi Goosestepping During Live Concert

N.E.R.D. frontman Pharrell Williams broke into a full-on goosestepping Nazi salute during a concert in Vegas this week ... and TMZ has obtained the footage.

Pharrell's people say to us, "You can't see it because his hand isn't in the picture, but Pharrell is throwing up the Star Trek sign, which is also the sign for his record label, Star Trak. To suggest that he is doing anything else is wrong and downright silly."
